Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to an exhaust device for a magnesium alloy die casting mould. Background Art

[0002] Die casting is a method of casting liquid die forging, a process completed on a special die casting die forging machine. Its basic process is that the molten metal is first cast and filled into the mold cavity at a low or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools, eliminating the shrinkage and porosity defects of the blank and making the internal structure of the blank reach the broken grains of the forged state.

[0003] During the die-casting process, the gas in the mold cavity needs to be discharged. If the gas in the mold cavity is not discharged, the workpiece processing quality will be affected. However, most of the existing die-casting molds directly discharge the high-temperature gas in the cavity, which is not only easy to burn the staff, but also poses certain safety risks. At the same time, the gas is directly discharged without filtering, and some harmful substances or dust impurities in it will also affect the environment. In summary, the existing exhaust devices still have the following problems:

[0004] 1. The high-temperature gas in the mold cavity is directly discharged, which can easily burn the staff; 2. The gas is directly discharged without filtering, which will also affect the environment. Utility Model Content
